Mobile screen design is a multi-phase process. You do not produce screen specs until you understand the platform, the user, and the flows. This skill has 5 phases. Move through them in order. Do not skip phases.
Before any visual work, you need to understand the context. Ask these questions. Lead with the most critical ones and follow up if needed. You do not need to ask everything in one message.
Done when: You know the platform, the flows to design, and have enough brand context to write a brief. You do not proceed without at least the platform, the flow list, and a brand direction.
Write back a short brief and ask the client to confirm it before you proceed. Every design decision will be evaluated against this brief.
Format:
Platform: [iOS / Android / Both — and which is primary]
App type: [one sentence describing the app and audience]
Flows to design: [numbered list — each flow as a verb phrase, e.g. "2. User completes checkout"]
Screens in scope: [total count]
Brand direction: [color palette, type, existing system or "TBD"]
Device priority: [e.g., iPhone 15 Pro / 390pt width, standard Android / 360dp]
Accessibility: [baseline platform + any additional requirements]
Out of scope: [anything explicitly excluded from this engagement]
Do not start visual work until the client confirms this brief.
Before any screen spec, state the platform rules that apply to this project. This is not boilerplate — it is a constraint checklist you will enforce in every screen you design. Acknowledge which rules apply and which are not relevant given the brief.
.sheet, .fullScreenCover) before designing custom overlays. Sheets are dismissible by swipe-down by default — do not design away this behavior.prefers-reduced-motion / Reduce Motion equivalent. Do not design flows that depend on animation to communicate meaning.State this platform checklist explicitly before proceeding to Phase 4. Confirm which rules are in scope.
For each screen in the confirmed brief, produce a complete spec. Do not produce only the happy path. Do not batch all screens before speccing states — complete each screen fully before moving to the next.
Screen: [Name — as a verb phrase describing user goal]
Platform: [iOS / Android / Both]
Entry point: [How does the user arrive here?]
Exit points: [Where can the user go from here? List all.]

LAYOUT
[Top zone — status bar through nav bar/toolbar]
- Component: [Navigation bar / App bar / None]
- Left action: [Back / Close / Menu / None — with label]
- Title: [Screen title text, or None]
- Right action: [Action label or icon — or None]
[Content zone — scrollable or fixed]
- Scroll behavior: [None / Vertical scroll / Paged]
- Component hierarchy (top to bottom):
1. [Component name] — [description, content, purpose]
Spacing above: [Xpt/dp]
2. [Component name] — [description, content, purpose]
Spacing above: [Xpt/dp]
[continue for all components]
[Bottom zone — primary action + safe area]
- Primary action: [Button label, style: filled/primary]
- Secondary action: [Button label, style: outlined/text — or None]
- Safe area clearance: [Yes / N/A]
──────────────────────────────────────────────────────────────────
COMPONENT DETAIL
[For each non-trivial component, specify:]
- Dimensions: [Width × Height in pt/dp, or % / fill]
- Touch target: [Confirm ≥44pt iOS / ≥48dp Android — flag if non-interactive]
- Typography: [Element — Scale name — Weight — Color token]
- Color tokens: [Surface / On-surface / Border / etc.]
- Corner radius: [Xpt/dp or system token]
- States: [Default, Pressed, Focused, Disabled — note visual change per state]
──────────────────────────────────────────────────────────────────
STATES
Empty state:
- Trigger: [When does this appear?]
- Illustration: [Describe or specify None]
- Headline: [Text]
- Body: [Text]
- CTA: [Button label and action — or None]
Loading state:
- Trigger: [When does this appear?]
- Skeleton: [Describe which elements show skeleton loaders]
- Spinner: [If full-screen, describe placement]
- Minimum duration: [e.g., show for at least 300ms to avoid flash]
Error state:
- Trigger: [When does this appear? e.g., network failure, validation, 4xx/5xx]
- Message: [User-facing error text — not a technical error code]
- Recovery action: [What can the user do? e.g., "Retry", "Go back", "Contact support"]
- Inline vs. modal: [Is the error shown inline or in a sheet/dialog?]
Success state:
- Trigger: [When does this appear?]
- Feedback: [Toast / Banner / Inline confirmation / Full screen / Animation]
- Next step: [Where does the user go after success?]
──────────────────────────────────────────────────────────────────
ACCESSIBILITY
- VoiceOver / TalkBack label for each interactive element
- Reading order: [Default (top-to-bottom) or specify custom]
- Any non-standard roles (e.g., custom toggle announced as "Switch")
- Minimum contrast: [Confirm text meets 4.5:1 AA or note exception]
After all screens are specced, produce a summary deliverable document.
App: [Name]
Platform: [iOS / Android / Both]
Design date: [Today's date]
Screens in scope: [N]
SCREEN INDEX
1. [Screen name] — [one-line description of user goal]
2. ...
COMPONENT LIST
[All named components used across screens]
Component: [Name]
Appears on: [Screen names]
Variants: [Default, Loading, Error, Empty, Disabled — check which apply]
Touch target: [Confirmed minimum]
Notes: [Any cross-screen behavior or constraints]
STATE MATRIX
[Table mapping every screen × every state]
Screen | Empty | Loading | Error | Success
─────────────────── | ───── | ─────── | ───── | ───────
[Screen 1] | ✓ | ✓ | ✓ | ✓
[Screen 2] | — | ✓ | ✓ | —
[...]
✓ = specced | — = N/A (confirmed) | ✗ = missing (flag for follow-up)
PLATFORM COMPLIANCE SUMMARY
Touch targets: [All pass / N exceptions — list them]
Safe areas: [All clear / N exceptions — list them]
Dark mode: [Specced / Not yet specced]
Reduced motion: [Addressed / Not yet addressed]
Contrast: [All pass / N items need check]
OPEN QUESTIONS
[Any decisions deferred, constraints unclear, or content TBD]
1. [Question — who owns the answer]
The deliverable is complete when: every screen in the brief has a full spec, every state is accounted for (or marked N/A with rationale), and the state matrix has no ✗ entries.
